The ad network is rolling out a new version of Chrome today which adds the option of pausing Flash and other content. This feature is coming to the desktop Beta channel starting today, and it will shortly be rolling out to all Chrome users on Windows and OSX.
Once you have the update, browse any webpage with a Flash script and Chrome will pause any content which isn't a key part of the webpage while letting other Flash animation (like a Youtube video) continue to play. If Chrome accidentally pauses something you were watching, you can just click it to reactivate it and continue playback.
Google says that the new feature is optional. You can go into settings and set the priority:
They also say that this feature is going to significantly reduce battery drain, but I'm not so sure that is true (or rather, it's not going to help me any).
Even though I use Ghostery to (among many other uses) prevent Flash from running uninvited, Chrome is doing terrible things to my battery life. I've tested it on several occasions and Chrome has cut my battery life by up to a third.
Given that I am usually plugged in somewhere, this is not a serious issue. But I would appreciate it if Chrome would let me have the battery life which Dell promised when I bought this laptop.
And that might happen later this year. Today's new Chrome feature isn't going to help me, but Google is also hinting that they will announcing more Chrome battery fixes over the coming months. With luck, one of those fixes should help.
